The Do-Over

Holly and Alicia Lilac Wayne are daughters of the famous multi-millionare Bruce Wayne. After living with their dad in the Wayne manor, Bruce decides that the girls should start over, creating new lives by themselves. Both sisters are complete opposites besides the fact that their mothers died.
Holly is the oldest, and was the result of a one-night-stand between her dad and her best friend's mom. Growing up with her father and developing her mom's witchcraft powers, she becomes BatJunior, Batman's second sidekick.
Alicia Lilac, the youngest, named after her mother, Alice, grows up in her mother's kingdom, a kawaii potato city of happiness and cuteness as the potato queen's servant, becoming like the queen's daughter. She also got her kawaii powers from her mother and uses the to fight crime with her family, earning the name "BatTato".
The sisters move to MyStreet, meet a supposedly "dead" man, and everything is going great. So what's the big deal when their dad remarries?
